FirmwareUpdateFATFile always returns the status ROM is invalid
« on: November 30, 2022, 01:11:00 AM »

Using the project FirmwareUpdateApp as an example in my code below. Using either the function FirmwareUpdateFATFileFeedback or FirmwareUpdateFATFile the both don't accept the ROM files.  I have used ROMs from my own projects and even the ROMs from install of Vinculum II IDE install 2.

First I have flashed the reflasher using:
VinPrg.exe ReflashFATFile.rom -o 0x1f000 -d "VII Debugger Module"

Then I run my application, select a ROM file that the linker has created and immediately returns from the FirmwareUpdateFATFileFeedback call.  The status is the ROM is invalid.

The return from the updating function is always FIRMWARE_UPDATE_INVALID_FILE.
Any suggestions what could be going wrong?


       file = fopen("FWUPDATE.ROM", "r");

   if (file == NULL)
   {
      puts1USART("@File not found@");
   }
   else
   {
      puts1USART("@Calling firmware update@");
      //#define REFLASHER_OFFSET 0x1f000
      //#define FEEDBACK       FIRMWARE_UPDATE_FEEDBACK_UART | FIRMWARE_UPDATE_FEEDBACK_GPIO_A2
      //status = FirmwareUpdateFATFileFeedback(file, REFLASHER_OFFSET, FEEDBACK);
      status = FirmwareUpdateFATFile(file, REFLASHER_OFFSET);
      
      if(status == FIRMWARE_UPDATE_INVALID_FILE) {
         puts1USART("@INVALID FILE@");
      }
      puts1USART("@Returned@");

      fclose(file);
   }

Hello,

This is the correct example to use:

C:\Users\Username\Documents\FTDI\Firmware\Samples\V2.0.2-SP2\General\FirmwareUpdate

Also refer to AN_159 Vinculum-II Firmware Flash Programming for more information.

Please note the restriction in the example readme:

Fragmented ROM files not supported. Do "CHKDSK <filename>" from command line to check.

This has been tested by FTDI and is working.

There may be other FTDI Community users who can help you further.

Best Regards,
